Sienna Miller was all smiles as she left rehearsals for Flare Path at the Haymarket Theatre in the West End yesterday. Wearing a green jacket she signed autographs happily for fans, before making her way to her car. Sienna's been hard at work preparing for the play lately, but she's made time for some fun too, going out with Tom Sturridge. She's also addressed her split from Jude Law, saying: "Apparently, we were engaged. . . We weren't. And I think this happens in everyone's lives: you get back together, you try and make it work, and it doesn't. It's not acrimonious, it had run its course." While Jude's been partying in Rio, Sienna now has the play to focus on, which starts on Saturday until June 4.
